4.1.6. Clock In/Out
The Clock input and output connectors on the back panel allow the KeyStep Pro to
synchronize with many different clock formats: a single pulse per step, two pulses per step,
24 pulses per quarter note (ppqn), and 48 ppqn.
These options enable you to connect and stay synchronized with almost every conceivable
piece of music technology.
4.1.6.1. Clock In/Out Rates
The downloadable MIDI Control Center can also be used to configure the KeyStep Pro
to send and receive one of the following clock signals via the Clock In and Clock Out
connectors.
4.1.6.2. Clock In/Out Connectors
Over the past few decades, several types of connectors have been used for musical
synchronization purposes. Here's a table that indicates the best kinds to use when
connecting older devices to KeyStep Pro:
Connector type
1/8'' mono (TS) [1]
1/8'' stereo (TRS) [2]
1/8'' stereo (TRS) plus DIN sync adapter [2]
You can use a 3.5 mm jack to 5-pin DIN adapters to connect to devices which utilize DIN
sync messages. Check the owner's manual for your device if you are not sure which sort of
sync capabilities it has.
1.
If Sync is set to an external source and a TS connector is used, the sequencer
needs to be armed before it can start when receiving a clock signal. You must
press the Play button to arm the sequencer. For example:
2.
If the Play button has been pressed but no clock signal has been received, the
unit will wait for a clock signal and only start when it receives one.
•
If clock signals are being received but Play is not active, the unit will start as soon
as you press the Play button.
•
If Sync is set to an external source and a TRS connector is used, the Keystep Pro
will follow the master and will:
•
Play on receiving a high-state signal and clock,
•
Pause on receiving a high-state signal and no clock, or
•
Stop on receiving a low-state signal, with or without clock.
